About
Florent Leroy
Excel Expert & VBA Developer · Freelancer since 2018

After several years as a consultant and data scientist for large corporations, I chose to dedicate my expertise directly to freelancers and SMEs. My conviction: a well-built Excel spreadsheet solves 80% of a small business's management challenges — without SaaS subscriptions, without a 3-month training course.

I have supported over 85 clients in 15 sectors of activity. Every tool I deliver is designed to last, evolve, and be used by non-technicians.

Concrete results, not promises.

🔨
Construction Tradesman
Thierry G., plumber-heating engineer, Toulouse
The problem

Thierry used to make his quotes from memory and sometimes found out at the end of the project that he had lost money on materials.

The solution

Job site dashboard with automatic margin calculation, tracking of actual expenses, alert if cost exceeds quote by more than 10%.

The results
Average margin increased from 12% to 24% in 4 months
3 hours saved per week on administrative tasks
0 unprofitable job since implementation
📊
Self-employed
Sophie L., freelance graphic designer, Paris
The problem

Sophie declared her turnover quarterly without knowing if she was approaching the VAT exemption threshold. She almost switched mid-quarter.

The solution

Turnover dashboard with automatic alerts at 80% and 95% of the threshold, and simulation of contributions based on turnover scenarios.

The results
Alert received in time — retroactive VAT avoided
Contributions better provisioned: +€350/month
Urssaf declarations pre-filled in 5 minutes
🏢
SME
Jean-Louis V., manager, company with 12 employees
The problem

Monthly reporting took his assistant 6 hours at the end of each month — manual consolidation of 4 files.

The solution

VBA macro for automatic consolidation + KPI dashboard with 18 indicators, threshold alerts, and automatic PDF export.

The results
Monthly reporting: 6h → 18 minutes
ROI achieved in 3 weeks
Zero consolidation errors for 8 months
